Gravity. If you want to know why you should look up Newton's laws of gravity all three of them.
The force of the Sun's gravity keeps them in their orbits.
The planets orbit the Sun. The Sun is at the center of our solar system and does not move.
The Sun's strong gravity keeps all the planets in orbit around it.
Gravity is the force that connects the solar system to the sun.
Planets in our solar system are kept in orbit by the gravitational pull of the sun. The balance between the centrifugal force of the planet's movement and the gravitational force of the sun keeps them in a stable orbit.
Gravity and motion. Gravity pulls the planets in and keeps them from flying away, while the velocity of the planets keeps them from being sucked in completely.
The Sun's Gravitational pull keeps the planets orbiting it, not flying into deep space.
The gravity of the sun an each moon's respective planet keeps them from flying into space.
The Sun's strong gravity keeps all the planets in orbit around it.
The suns gravitational pull.
The force of the Sun's gravity keeps them in their orbits.
The sun's gravity affects the motion and orbits of planets in our solar system by keeping them in orbit around it. The gravitational pull of the sun keeps the planets moving in their elliptical orbits, preventing them from flying off into space. The strength of the sun's gravity decreases with distance, so planets closer to the sun orbit faster than those farther away. This gravitational force is what keeps the planets in their stable orbits around the sun.
it keeps it in orbit
The suns gravitational pull keeps all the planets revolving around it. Without it, all the planets would go flying off into who knows where (including Earth) and the planets would of course crash into other objects and everything and everyone on Earth would die.
The planets orbit the Sun. The Sun is at the center of our solar system and does not move.
the sun because it keeps the planets in orbit and provides heat.
Gravity keeps the planets together
